Kite boarder David Sheridan skimmed just inches above the Southern Right whale off the north coast of Australia.
The dramatic shot was captured from above by his sail camera.
But just moments later David was knocked flying after the giant mammal flipped his tail to shoo the surfer away.
David said: "It all happened so fast that all I could do was crouch down as the whale swam under me.
"Next thing I felt was the tail come up and hit me on the back of the head."
Luckily David escaped unharmed.
